A made up word that can mean anything. No seriously, it originated from sailors (not pirates) that are totally pimp, and when someone asks, "Hey, what's up sailor?" in a weird voice, the reply would be "I'm docken." Which means it's going good.

It's sort of like how people say, "What's up, dawg?" and the reply is "Chillin'" or something like that. You can use it even if your ship isn't docked or anchored.

The coolest part about all of this is that you don't even have to be a sailor to use this word. Everyone can use it! Ninjas, Space Aliens, Illegal Aliens, Legal Aliens, Ninja Assassin's, Homies, Bros and even Super Mario!
